Abstract
By the data of cruise 54 of the R/V Akademik Mstislav Keldysh (September 2007), the results of geochemical studies of the redox processes in the bottom sediments of the Ob River’s near-mouth area as applied to the redox indicator elements such as manganese, iron, and sulfur are presented. The characteristics of the bottom sediments and the distribution of these elements in them testify not only to the significant role of the mixing processes in the formation of the geochemical profile of the bottom sediments in the estuary but also to the role of the postsedimentation (diagenetic) processes.
